Temperature difference for adjusting water in high-pressure washer
Thread Content
Why is a temperature difference of 15°C required between the inlet and outlet water in high-pressure scrubbers, and what are the consequences if this difference is too large?
From a design perspective, if the temperature difference of the high-pressure water is too large, the temperature of the high-pressure water entering the high-pressure washer may be too low, which can lead to crystallization at the inlet of the high-pressure washer.
It’s the CO2 stripping process, right? In fact, the temperature difference of the adjusted water is related to various factors such as the flow rate of the adjusted water, the inlet temperature of the adjusted water, the structure of the high-pressure scrubber, the ammonia-to-carbon ratio in the system, and the inert gas content in the system. Initially, the temperature difference for heating water was set at only 10 degrees; now, many devices have been modified to improve cleaning efficiency, with the temperature difference reaching over 20 degrees in some cases. If the temperature difference of the cooling water in production increases, it may be due to a high ammonia-to-carbon ratio in the system (as the ratio becomes too high, the temperature difference actually decreases), an increase in the amount of inert gas in the system, or excessive control of the pressure in the vapor drum of the high-pressure ammonium methanate condenser, among other factors; other parameters can also be taken into consideration for diagnosis.
As long as the inlet water temperature is properly controlled, a large temperature difference has little impact on the system; the temperature difference is merely an indicator of the system’s operating conditions. Generally, this temperature difference is not used as a basis for determining system failures. As mentioned on the third floor, other data such as system pressure, the temperature of the synthesis tower, and the temperature of the liquid coming out of the washing unit are taken into consideration when making judgments. If the temperature of the return water is too high, scaling can occur on the circulating water side of the water cooler, which may lead to vaporization at the pump inlet (though this is unlikely)
